ABC(XiSheng) Electronics Co.,Ltd MAC Prefix Identification
Summary
- // what this is
- ABC is registered to MAC prefix
5C:2E:D2in the IEEE OUI database. When a device's MAC address begins with5C:2E:D2, that block was registered by ABC — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The literal prefix fixes the first-byte Group bit and Local bit at zero. Matching is on the first 24 bits; 24 suffix bits allow 16,777,216 possible values, not an observed device count. A prefix match indicates a registry assignment, not a specific device, operating system, or security state.
About this vendor.
A MAC address beginning 5C:2E:D2 matches an IEEE MA-L assignment to ABC(XiSheng) Electronics Co.,Ltd; the assignment does not identify a specific device category. No supplied evidence connects this prefix to a particular product or device type.
The prefix fixes the first 24 bits of a 48-bit MAC address, leaving 24 suffix bits, or 16,777,216 possible suffix values. This is a count of possible values, not a device or shipment count. In the first byte 5C, the Group bit and Local bit are both zero. These bits are fixed for this literal prefix; changing either creates a different prefix. RFC 7042 describes the bits’ MAC-address significance and the relationship between OUIs and longer prefixes.
Assignment dates are unavailable in these IEEE CSV records.
